Gps Navigation System Using Neural Networks

View page
US Patent:
6351711, Feb 26, 2002
Filed:
Sep 14, 2000
Appl. No.:
09/662412
Inventors:
Mangesh M. Chansarkar - Sunnyvale CA
Assignee:
Sirf Technology, Inc. - San Jose CA
International Classification:
G06F16500
US Classification:
701213, 701214, 701200, 73178 R
Abstract:
A GPS receiver includes a satellite receiver/processor having an input that receives input signals from at least one GPS satellite. The output of the receiver/processor provides satellite-related navigation information. A neural network receives the satellite-related information to obtain an output signal representative of receiver-related navigation information. The neural network includes a first node layer connected to a second node layer through a first connection layer and a third node layer connected to the second node layer through a second connection layer. Each of the node layers comprises a plurality of neurons.

Spread Spectrum Receiver With Multi-Bit Correlator

View page
US Patent:
6393046, May 21, 2002
Filed:
Apr 25, 1997
Appl. No.:
08/846067
Inventors:
Sanjai Kohli - Manhattan Beach CA
Steven Chen - Cerritos CA
Charles R. Cahn - Manhattan Beach CA
Mangesh Chansarkar - Santa Clara CA
Greg Turetsky - San Jose CA
Assignee:
SiRF Technology, Inc. - San Jose CA
International Classification:
H04L 2330
US Classification:
375134, 375130, 375137, 375140, 375142
Abstract:
A terrestrial C/A code GPS receiver system digitally samples, filters and stores a segment of 11 half chips of the received composite as a binary number and multiplexes this number for parallel correlation with each of a series of multibit code replicas for the satellites to be tracked. Each of the time delay specific correlation products are accumulated in a cell of a memory matrix so that at least twenty two delays for each satellite may be evaluated each code period providing fast reacquisition, even within a city intersection, as well as correction of multipath tracking and multipath interference. All cells of the memory matrix may be used for a acquisition of a single satellite in about 4 ms. Two satellite tracking, in addition to altitude hold, uses cross track hold alternating with clock hold to update the cross track estimate. Single satellite tracking uses cross track and clock hold together.

Navigation System And Method For Tracking The Position Of An Object

US Patent:
6453238, Sep 17, 2002
Filed:
Sep 15, 2000
Appl. No.:
09/662559
Inventors:
Keith J. Brodie - Irvine CA
Stephen F. Rounds - Irvine CA
Mangesh M. Chansarkar - Sunnyvale CA
Assignee:
SiRF Technology, Inc. - San Jose CA
International Classification:
G01S 502
US Classification:
701216, 701300, 340988, 342457
Abstract:
A navigation system for tracking the position of an object includes a GPS receiver responsive to GPS signals for periodically providing navigation state measurement updates to a navigation processor. The system also includes a dead-reckoning sensor responsive to movement of the object for providing movement measurements to the navigation processor. The navigation processor determines object navigation states using the navigation state measurement updates and propagates the object navigation states between measurement updates using the movement measurements.

Resolving Time Ambiguity In Gps Using Over-Determined Navigation Solution

View page
US Patent:
6618670, Sep 9, 2003
Filed:
Sep 14, 2001
Appl. No.:
09/952548
Inventors:
Mangesh M. Chansarkar - Sunnyvale CA
Assignee:
SIRF Technology, Inc. - San Jose CA
International Classification:
G01C 2126
US Classification:
701213, 701207, 701214, 701215, 34235704, 34235706
Abstract:
The invention describes methods and apparatuses for determining a user position based on a minimization of the errors introduced into the GPS system because of clock bias, noise, multipath, or other uncertainties. By overdetermining position, for example, clock biases can be removed from the system.
